Medical image reconstruction is a key component for a broad range of medical imaging technologies. For classical Computed Tomography systems the amount of measured signals per second increased exponentially over the last four decades, whereas the computational complexity of the majority of utilized algorithms has not changed significantly. A major interest and challenge is to provide optimal image quality at the fewest patient dose possible. One solution and active research field towards solving that problem, are iterative reconstruction methods. Their complexity is a multiple compared to the classical analytical methods which were used in nearly all commercially available systems. In this thesis the application of graphics cards in the fi...
